Would it be possible to add a number line to mark off clues as done, not done, or to check back later? It would make it faster and easier to go back to those </> clues. (OK, I'll admit to wanting to mark them off because sometimes I miss clues as I go from clues list to grid and back. I'd like to think I'm not the only one.)

I'm embarrassed that I didn't figure out that handy little feature.
Thank you very much. I should be having fewer mess ups in the future. I owe you and will never again go all out to try to top you because you've just proven to me that you are tops.
